摘要
目的探索毒杀鼱的方法及效果评价。方法试验分为普通灭鼠毒饵、灭鼱毒饵A剂和B剂3个试验组。密度调查采用夹夜法,效果评定采用Suyuki的相关密度指数法。结果投放普通灭鼠毒饵前后鼠形动物密度下降率为30.06%,相关密度指数(RPI)值为97.96。投放灭鼱毒饵A剂前后密度下降率为77.47%,RPI为32.31;投放灭鼱毒饵B剂前后密度下降率为69.76%,RPI为22.22。结论灭鼱毒饵A、B剂在试验区投放后鼠密度下降明显,普通灭鼠毒饵的毒杀效果不理想。
Objective To evaluate the efficacy of poisoned bait against Suncus murinus. Methods Common rodenticide, new rodenticide A and B against S. murinus were used in three trials, respectively. To investigate its densities by snap-trap, and evaluate the efficacy of rodenticide by the Suyuki relative population index （RPI）. Results The density decreased 30.06% after treatment with common rodenticide, and the RPI was 97.96. However, after treatment with the new rodenticide A and B against S. murinus, the density decreased 77.47% and 69.76% respectively, and the RPI was 32.31 and 22.22 respectively. Conclusion The new rodenticide A and B against S. murinus had good efficacy on the decrease of rodent densities, and that of common rodenticide was not good.
